Notes:
1.
The system supports
NO LOCK
and
NC LOCK
. For example the
NO
LOCK
(normally opened at power on) is connected with '
NO1
' and
'
COM1
' terminals, and the
NC LOCK
(normally closed at power on) is
connected with '
NC1
'and '
COM1
' terminals.
2.
When electrical lock is connected to the Access Control System, you
must parallel one FR107 diode (equipped in the package) to prevent
the self-inductance EMF from affecting the system.
Do not reverse the polarities.
